Roundup Weed & Grass Killer4 Concentrate is a mix-it-yourself concentrate that kills tough weeds and grasses to the root, including dandelion, large crabgrass, poison ivy, red and white clover, spotted spurge and other broadleaf weeds. It is rainproof in as fast as 30 minutes and produces visible results in hours.

• Active ingredients: triclopyr, triethylamine salt 2.50%; fluazifop-P-butyl 2.00%; diquat dibromide 1.50%
• Mixing: 6 fl oz per gallon of water for best results and for tough weeds, perennials, brush and vines; 3 fl oz per gallon for small, newly emerged annual weeds under 3" tall
• Each gallon of spray solution treats up to 300 sq ft
• Apply with a tank sprayer, or with a hose-end sprayer for large areas (pour the concentrate into the jar undiluted and set the dial to 3 or 6 oz)
• Allows planting 1 to 30 days after application - see the label booklet for the specific plant
• Use in flower beds, around trees and shrubs, along fences, foundations and retaining walls, on patios, driveways, walkways, gravel and mulch beds, on freshly cut woody stumps, and for lawn replacement or garden plot preparation

Tip: For best results apply at the 6 fl oz rate in warm, sunny weather above 60 deg F, when the air is calm. Results can be slower in cool or cloudy weather or at the 3 fl oz rate. Some established perennial or hard-to-kill weeds may need a repeat application; wait at least 28 days before reapplying.

Caution: This is a non-selective weed and grass killer - do not spray plants or grasses you want to keep, and do not use it for spot weed control in lawns, because it kills lawn grass. Shield nearby plants from drift with cardboard or plastic. Do not use on or around edible food or feed crops, or where livestock graze. Do not apply with a backpack sprayer. Keep people and pets out of the treated area until the spray has dried. Always read and follow the product label.
